With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts which will be hereinafter more it being understood that various changes may be made in the construction and operati on of the parts without departing from the spirit of the invention as set forth in the ap' pended claim. I In the accompanying drawings the preferred form of the invention has been shown.

Fig. 5 is a detailed view of one of the Referring to the figures by characters of reference, 1 designates a hopper like casing having an inclined bottom leading down wardly to an outlet provided at the front of the casing and shown at 2. Within the up- .per ortion of this casing is secured a supporting plate 3 in which are formed coin outlet openings 4, 5, 6 and 7 arranged in pairs. The apertures 4 and 5 are adapted to receive and permit the discharge of nickels" Specification r Letters Patent.

is slightly greater than that of a nickel,

the thickness oftheplate 8 being equal to or slightly less than thethickness of twov nickels. An arm 10 is extended inwardly from the plate 8 and I 11 to the upper end of a bell crank lever 12 fulcrumed on a pin 13 which is extended through and supported by flanges 14: extending inwardlyfrom' the front wall of the casing. The lower end of the lever 12 is eX- tended forwardly through a slot 15 in the front wall of the casing and is provided at its free end with a key on which the numeral 10 may appear, indicating ten cents.

Another-segmental plate 16 is pivotally mounted on the plate 3 near the opening 5 and has an opening therein slightly greater in diameter than a nickel, and thickness of the plate 16 being equal to or slightly less than the thickness of one nickel. This opening has been shown at 17. The plate is pivotally mounted at 18 and has an arm 19 extending radially therefrom back of and in the path of thearm 10. A stud 20 is provided on the end of arm 19 and engages one end of a link 21 the other end of which engages the upper end of a bell crank lever 22 which is similar to the lever 12 and is mountedon the pin 13. The lower arm of this lever projects forwardly through the slot '15 and has a key on its end on which the numeral 25 may appear as designating twenty-five cents.

Pivotally mounted on the plate 3 adjacent the opening 6 is another segmental plate 23 having an opening 24 therein the diameter of which is slightly greater than the diameter of a dime, this plate being of a thickness equal to 0r slightly less than the thickness of a dime. An arm 25 is extended inwardly from the plate 23 and is connectedby a link 26 to the stud 20. 9

opening 7 is a segmental plate 27 having an opening 28 therein the diameterof whichis slightly greater than the diameter of a quarter and the thickness of this plate is equal to or slightly less than the thickness of a quarter. Thisplate has an arrn 29 extending inwardly therefrom and back of the arm 25 with which it normally contacts. Stops 30 are provided adjacent openings 4 and 7 for limiting the movement of the plates 8 and 27 when swung inone direction.

A link 32 is connected to the arm 29 and extends forwardly over the arm 19 and is Pivotally mounted on the plate 3 near the is connected by a link 1 in said plate, is'a' and against the stop 30.

nickels contained in the opening 9 will be slid from under the container 3 5 and secured to the upper end of a bell crank lever 33 which is mountedon the pin 13and has a key on its fOrwardIyeXte iiding lower portion, said key bearing the numeral 50, designating a half dollar.

Secured on the casing l is a cover plate through which extend tubular coin containers 35, 36, 37 and 38. The containers all terminate close to the upper faces of the segmental plates thereunder and the containers and 36 are a da ted'to hold nickels while the containers 3 and 38"are designed to hold dimes and quarters, re spectively.

Secured to the bottom of the plate 3 and extending" forwardly between the openings spring 39 secured to the intermediate portionof an equalizing lever 40. A smaller lever 41 is pivoted at its center on one end portion of the lever 40. A link 42 connects one end of lever 41 to the upper portion of lever 12; Another link connects the other end of lever ll to the upper portion of lever 22 and a third link 44 connects the other end portion of lever with the upper portion of the lever 33. Thus it will be seen that the pull exerted by the spring 39 will be equalized' upon the levers 12, 22 and 33 and said levers normally maintained with their keys elevated and with the plates 8, 16, 2-3 and 27 posi- .tioned as shown in Fig. 2.

When the parts are positioned as illustrated'fthe lower coin in each of the containers 36, 37 and 38 will rest in the apertured segmental plates under said'containers while the two lower coins in the container 35 will rest in the aperture 9, all of said coins being supported by the plate 3.

Should it be desired to deliver change for a dime, the key lever 12 is depressed This causes the plate 8 to swing upon its pivot Thus the two brought to position over the opening 4 through which they will fall into the bottom portion of the casing 1 and gravitate to the out'let 2. The stack of coins in the 2 container 35 will be supported by plate 8 until the plate retilrnsto its normal position whereupon two more coins will become seated in the opening Change for a quarter is obtained by depressing the'le've'r 22. Link 21 thus pullsi through link 26 and both plates 16' and '23 are actuated to c ieroz om patent m be obtained for bring the contents of their openings 17 and 24; to the openings 5 and 6 respectively. At the same time the; arm 19 of plate 16 moves against the arm '10 of plate 8 and causes said plate to deliver its contents to the opening at. Thus at one operation two nickels will be delivered through opening 4:, one nickel through opening 5 and one dime through opening 6. By depressing lever 33 the link 32- will pull on arm 29 and shift plate 27' to delivering position. This arm 29 will push against and actuate the arm 25 which, in turn,- will thrust through link 26 against arm 19 which will actuate the arm 10. Therefore the contents of all four segmental plates will be delivered simultaneously into the bottom portion of the casing and will be the proper change :for one half a dollar.

It is to be understood, of course, that the machine can be changed readily to adapt itself for use with coins other than those described.

What is claimed is In change making apparatus the combination with separate key levers, an equalizing being arranged in pairs and having arms,

one arm of each pair beingvarranged in front of the other arm of said pair whereby actuation of i one of the uncoupled plates will cause transmission of motion through the arms and coupling connection to all of the remaining plates, one of said unconnectedplates being shiftable independentlyof the reniaining platesand also with all but one of said remaining plates.

I n testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presenceof two Witnesses.
